Available to hire
Hi there! I’m Sebastian Lopez, a dynamic UX Designer and Game Designer with over 8 years of experience creating engaging game experiences in Unity and Roblox. I’ve led design teams and helped shape the product vision for Adventure Forge, working with brands such as Intel, Cartoon Network, and Sesame Street. I’ve contributed to UX, user interfaces, and demo content for multi-platform game tools while maintaining a strong focus on documentation, playtesting, and delivering a solid MVP.
I’m passionate about crafting intuitive interfaces, designing compelling game systems, and mentoring teams to ship quality experiences. I enjoy turning ideas into playable prototypes, iterating from data and user feedback, and communicating design direction clearly to artists and engineers alike.
